Truly one of those questions that I am asked way more than I could ever manage to answer. Too many games vary so distinctively and in a way that I could never properly judge one of them as being better over all of the others simply because they're nothing alike. Even if you force me to put up games from the same basic genre, you'll still get extremely creative titles that make it hard for me to justify putting one on top of the other, let alone all of the different pros and cons that factor in on a personal scale. All I can really do is list off a couple of games that really hit me hard or ones that I've just come to love extremely dearly over my lifetime, whether it'd be for the slick gameplay, the wonderful world building, amazing visuals, heart-wrenching moments, or just my own experiences playing them. All of these games have caveats whether small or large, but I personally feel like they shine in their own rights for what they excel in, and they're sometimes notable influences in my own creative designs as well.

Spoiler: I tried to keep it limited to one game a series at the very least..
